Specification of Letters Patent.

Patented Sept. 39, 1913.

Application filed July's, 1912. Serial No. 708,247.

To .ZZ whom it may concern Be it known that I, MICHAEL E. SHAW, a citizen of the United States, residing at Maplewood, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in Tile-Machines,

of which the following is a specification.

This invention. relates to machlnes for making tiles, and its object is to provide a.

simple, inexpensive and easily operated machine of this kind, and also one which can be operated manually or by power.'

This invention also has for its object to provide novel means for supporting the mold in which the tile is formed, and also to pro vide novel and improved means for operat ing a packer which acts in conjunction with the mold.

Other objects and advantages of the invention will be pointed out in the detaile description appearing hereinafter.

In order that the invention may be better understood, reference is had to the accompanying drawings, in which Figure 1 is an elevation of the machine;

Fig. 2 is a similar yiew taken from the opposite side. Fig. 3 1s a horizontal section on the line 33 of Fig. 1. Fig. 4 is a trans- I verse section on the line H of Fig. 3, and

Fig. 5 is a detail of one of the gears to be hereinafter referred to.

Referring specifically to the drawings, the;

, to one of its ends a crank or drive pulley 18,

and at its other end a bevel gear 19. On the cross-bars 14 and 15 are vertically alined bearings 20 in which is journaled a hollow vertical shaft 21 on which is fast a bevel gear 22 which is in mesh with the bevel gear 19. The shaft 21 also carries a sprocket wheel 23 which is connected by a chain 24 with a sprocket wheel 25 on a short vertical shaft 26 supported in hearings on the crossbars 14 and 15. On the shaft 26 is a worm 27 which is in mesh with a worm-wheel 28, the latter also being in mesh with a vertical rack 29 to the upper end of which latter the corresponding end of a shaft 21 is made fast, said shaft passing through the shaft 21 and carrying the packer to be presently described. The shafts 21 and 21 turn together, the former having a key which extendsinto a key way in the latter, and which. allows the shaft 21 to be moved in the direction of its length, for a purpose to be hereinafter described.

The gearing herein described rotates the drive shaft 17 is actuated To the bottom of the rack 29 is secured one end of a rope or cable 30 which passes over guide pulleys 31 and has connected to its other end a weight 32.

The worm-wheel 28 is carried by a vertical bar 33 secured to the cross-bars 14 and 15, and is slidable so that it may be disconnected from the worm 27 and the rack 29, and to facilitme this operation, the wormwheel is provided with a knob or handle 34. On the lower end of the rack is a handle 35 to facilitate the manual operation thereof when the worm-wheel is disconnected, as will be hereinafter described.

The packer which is carried by the lower end of the shaft 21 comprises a cylindrical bottom portion 36 and a conical head 37, and it is made fast to the shaft by a set screw 38. To the head of the packer are fastened, by bolts 39, diametrically opposite outwardly projecting wings 39 having curved extremities. These wings are ad- The mold is a sheet-metal cylinder 40 which is split longitudinally so that it may be spread or contracted, a suitable lever 41 being provided for this purpose which also looks the cylinder in closed or contracted position. The bottom of the cylinder rests on a pallet 42 having an upstanding annular flange 43 within which the cylinder snugly fits. Pallets of various sizes to suit the diameter of the cylinder, and difierent sized cylinders, according to the size of the tile to be molded, may be provided.

The pallet 42 is carried by a horizontally swinging table 44 the latter being carried by a vertical rod 45 supported at its upper end in a suitable bearing 46 on the crossbar 14, the lower end of the rod passing through a hole in the sill 12. The rod 53 rotatable to swing the pallet and the mold into and out of working position, and said rod also movable in the direction of its length to raise and lower the mold, for a purpose to be hereinafter pointed out. The table has an upstanding annular flange 17 within which the pallet seats. Set screws 48 are threaded through this flange and bear against the outer edge of the pallet 42 to hold the same properly centered. The table has two seats so that two mold cylinders may be employed when the machine is in operation, one cylinder after the other being filled.

The upper end of the mold cylinder 40 extends into a hopper 4-9 carried by a bracket arm 50 mounted on one of the uprights 10. In the hopper is mounted a member 51 similar to the pallet 42 and engageable with the top of the mold cylinder. Set screws 51, threaded through the hopper and bearing against the outer edge of the member 51, hold the upper end of the mold cylinder properly centered.

In order to insert the upper end of the mold cylinder 40 into the member 51 and to remove the same, the table 44 is mounted so that it may be raised or lowered as hereinbefore described. For the purpose of raising and lowering the table, there is provided a hand-lever 52 which is pivoted to a collar 53 rigidly mounted on the rod 455, and

I connected intermediate its ends to a vertical in either direction, one of the uprights 10 being in the path of these lugs. This upright also carries alatch 56 for locking the table, the latter having notches 57 in its rim into either one of which the latch slips according to the position to which the table is swung.

On the sill 12, in axial alinement with the shaft 21 is mounted a set screw 58, the function of which will be presently described.

In operation, the pallets 12 and mold cylinders 10 are placed on the table -14, and the latter is swung around so that one of the cylinders comes into position directly beneath the member 51 in the hopper ii), the table being first lowered so that the cylinder may come beneath the hopper. The table is now elevated to insert the upper end of the cylinder into the member 51, and the set screws 48 and 51 are applied. The

worm-wheel 28 is now disconnected, and the rack 29 is lowered to bring the. packer into the cylinder, the packer being lowered therein until it is even with the pallet 42 and rests on the set screw 58. The table has openings 59 within the flanges4=3 to permit the packer to be lowered, as stated, and in the pallet 42 and member 51 are central openings 60 for the same purpose. The cylinder is now filled and the worm-wheel thrown in gear, whereupon, when the drive shaft 17 is put in motion, the packer is m tated and gradually raised in the cylinder. The' weight 32 balances the packer and makes it easy to operate. The packer acts as a core to shape the interior of the tile. The wings 39 press the material outward against the inner surface of the cylinder and it is thoroughly compacted. The packer is raised slowly until it leaves the cylinder, the tile being then finished. The table 4. is now lowered to take the cylinder out of the member 51, after which the table can be swung around to remove the cylinder from beneath the hopper and to place the next cylinder in filling position.

I claim:

1. In a tile machine, a supporting frame, a rotatable and longitudinally movable rod carried by said frame, a mold supporting table carried by the rod, a lever pivoted to the rod, and a stem to which the lever is connected intermediate its ends, said stem being loosely engageable with the support. ing frame.

2. In a tile machine, a support, a rotatable and longitudinally movable rod, a mold sup porting table carried by the rod, a lever I pivoted to the rod, a stem to which the lever is connected intermediate its ends, and a pivoted section carried by the stem and passing looselythrough the table to engage the support.

3. In a tile machine, a cylindrical mold, members engageable with the ends of the cylinder and having annular flanges within.

which said ends seat, supports for said members, and set screws threaded through MICHAEL E. SHAW.
